2025-09-09T05:00:00Z
The Environmental Protection Agency (EPA) published the Spring 2025 Semiannual Agenda of Regulatory and Deregulatory Actions on August 30, 2025. The agenda outlines the agency’s upcoming regulatory actions and their status in the rulemaking process.
EPA has major updates on the docket, such as:
- Repealing all greenhouse gas (GHG) standards for fossil fuel-fired power plants and the 2024 amendments to the Mercury Air Toxics Standard for power plants (final rules expected December 2025);
- Establishing risk management rules for multiple chemical substances, such as 1-bromopropane and n-methylpyrrolidone (final rules expected April 2026);
- Adding hazardous waste solar panels to the federal universal waste program and setting universal waste standards specific to lithium batteries (proposed rule expected February 2026);
- Setting the Renewable Fuel Standards for 2026 and 2027 and implementing regulatory program changes (final rule expected October 2025); and
- Reconsidering current rules, like:
- The GHG Reporting Program (final rule expected November 2025),
- The National Emission Standards for Hazardous Air Pollutants (NESHAP) for iron and steel and the NESHAP for oil and natural gas (proposed rules expected November 2025 and December 2025, respectively), and
- The 2024 amendments to the procedures for conducting Toxic Substances Control Act chemical risk evaluations (final rule expected April 2026).
Additionally, the agency intends to address per- and polyfluoroalkyl substances (PFAS) across multiple media. For example, EPA plans to:
- Rescind the National Primary Drinking Water Regulations for PFHxS, PFNA, GenX, and mixtures of these three as well as for PFBS (proposed rule expected September 2025);
- Add certain PFAS to the Toxics Release Inventory (final rule expected February 2026); and
- Address PFAS discharges from PFAS manufacturers (proposed rule expected January 2026).
This article highlights some of the major rules we’re monitoring closely. You can review the entire agenda to learn about all the rulemakings on EPA’s docket. Please note that the agenda dates are tentative, indicating when the agency seeks to publish the rulemakings in the Federal Register.
